In the context of the classic SI, SIS, and SIR epidemiological models, which of the following statements is incorrect ? A. In the Susceptible-Infected (SI) model, each individual in the population is assumed to be either healthy or infected B. In the Susceptible-Infected-Susceptible (SIS) model, an individual who becomes infected with the disease can recover and return to the susceptible state, allowing reinfection C. In the Susceptible-Infected-Recovered (SIR) model, individuals who have been infected acquire immunity or die from the disease and therefore do not become susceptible again D. Assuming a transmission rate of β〈k〉 and a rate of recovery of μi, all three models predict that the epidemic ends only after every individual has been infected at least once E.

Regarding the robustness of complex networks, which of the following statements is false ? A. A network with maximal robustness has a hub-and-spoke topology, with bimodal degree distribution B. Scale-free networks with γ > 3 behave like random networks with respect to random failures C. In comparison with random networks, scale-free networks have enhanced robustness D. Hubs ensure robustness against random failures, but make networks vulnerable to attacks E.
